BACKGROUND Field of Invention and Prior Art

A. Introduction of the Problems Addressed

Prior devices and methods included metallic and other complex fluidpumping systems. One skilled in the art and familiar with such meanswell appreciates the simplicity and cost effectiveness of this newdevice presented here. In the other prior art disclosures shown, complexand expensive alternatives are demonstrated. These are not only costlyto manufacture but bulky, and difficult to use in the process of pumpingfluids.

Conventional systems are known for removing fluid such as water or oilfrom wells where there is an abundant supply of fluid. However, inshallow locations or locations with a low production volume, thesesystems may not be cost justified. For example, in oil formations up to1000 feet deep or more which only produce a few barrels of oil per day,multiple oil wells are often situated close together. Equipment andmaintenance costs are often economically prohibitive in shallow wells.

Furthermore, due to pressure, chemical conditions, and sand and grit inmost oil wells the equipment is subject to high breakdown rates andrequires frequent maintenance, repair or replacement. Consequently,particularly for a shallow, low production situations, there is a needfor inexpensive, low maintenance pumping systems that can be efficientlyinstalled and/or removed if necessary. Prior approaches to this type ofpumping system have involved complex piping and pumping systems,hydraulics, controls, sensors and electronics normally lowered into thewell. This results in complex installation and high costs forinstallation, maintenance and replacement.

B. Prior Art

One approach to a pumping system is shown in U.S. Pat. No. 4,653,989issued to Mason. Mason shows a series of pneumatic displacement chambersconnected to an air compressor at the surface of the well, by a singleair line. Each chamber is connected to the air line through a motorizedvalve. A float including a disk shaped magnet, rides up and down in eachdisplacement chamber. When fluid fills the chamber, the float approachesthe top and the magnet is detected by a sensor which causes the controlsystem to open the motorized valve connecting the chamber to the airline. Once the motorized valve is open, compressed air forces the fluidinto the next chamber, or alternatively, into a holding tank on thesurface. As the float approaches the bottom of the chamber, the magnetis detected by a sensor which causes the control system to close themotorized valve connecting the chamber to the air line. The Mason patentadditionally teaches that the float be provided with flutes between itslower surface and the internal surface of the chamber to avoid thepossibility of the float being used as a valve. The design of the Masonpatent is costly and complex, requiring a magnetic sensor system locateddown hole and a motorized valve in connection with each chamber of thewell pump, in addition to other shortcomings.

Another well pump is shown in U.S. Pat. No. 4,050,854 to Hereford et al.The Hereford patent shows a well pump including chambers that are costlyand complex, among other disadvantages.

Earlier versions with some similarities to the currently improved pumpare the US patents issued to Marvel et al. hey include U.S. Pat. No.6,435,838 issued in 2002, U.S. Pat. No. 6,558,128 issued in 2003, andU.S. Pat. No. 6,810,961 issued in 2004. All these described considerablyheavier assembles and little use of plastic materials. They were alsolimited to much shallower wells than the present device shown herein.

There remains a need for a simple, efficient, low cost, low maintenancepumping system that can be installed, repaired and/or removedefficiently and inexpensively in a well. The present invention addressesthese needs, among others. As far as known, there is no other ImprovedFluid well pumping system at the present time which fully provide theseimprovements and functional characteristics as the present device. It isbelieved that this device is made with fewer parts and with improvedconfigurations and physical features to provide more functionality whencompared to other currently utilized devices or methods to provide pumpliquids and gases as described herein. The particular combinations ofmaterials and features are unique and novel. They are not anticipated byprior art. Likewise unique is the method to secure and process thevarious parts of the Improved Fluid well pumping system.

SUMMARY OF THE INVENTION

A Improved Fluid well pumping system items is comprised of a pumpassembly (located in the wellbore) and a control system (located on thesurface).

-   -   A. The pump assembly consists of a series of fluid chambers        connected by line assemblies and separated at up to 250 ft        apart. Each line assembly consists of three internal lines which        include one (1) fluid production line and two (2) gas lines. The        internal lines are made of a coiled high density polyethylene,        which provides durability up to 200° F. and wellbore pressure of        200 psi. The lines are connected to alternate chambers using a        closed design that assures no gas/air is released into the        wellbore.    -   B. The control system consists of a compressor (which generates        compressed gas to push the fluids up) and a microprocessor        controlled valving system (which directs fluids flow through the        pump and into the production facility).

The preferred embodiment of the device is comprised of a durable yetsomewhat flexible and non-corrosive material with features andcharacteristics that permit easy securement of the components of thedevice.

The pump technology that is being improved consists of

-   -   NOJAK's artificial lift design technology that deploys a        pressure actuated chamber technology to lift hydrocarbons and        other fluids (i.e. brines) from the well bore to the surface.    -   The design of the NOJAK pump that was developed around the        pressure actuated chamber technology and is the first of its        kind to be commercialized.    -   The NOJAK pump that has the capacity to pump approximately 20 to        180 BPD at a depth of 500 to 4,000 ft.    -   Compared to existing artificial lift technologies, the NOJAK        pump that differentiates itself by eliminating down hole wear        out components/precision parts while requiring minimal        maintenance for surface equipment.    -   The Department of Energy (“DOE”) has recognized that the NOJAK        pump has a “green” alternative to current artificial lift        technologies available in the market and has granted        approximately $250,000 to further develop the technology.

Pressure Actuated Chamber Technology . . . How it Works?

Typically, a NOJAK installation in a 1,000-ft well will requirecompressed air/gas flow rates of about 30 to 50 cfm. When pressure isapplied (from the compressor) to the uppermost fluid chamber, the fluidis forced up through the uppermost line assembly into the flow line atthe surface to the production facility.

Stage 1:

-   -   The fluid inlet (filter screen) and the bottom fluid chamber of        the NOJAK system are set to operate below the pumping fluid        level of the well. This stage fills using bottom hole pressure        as an internal check valve prevents fluid from draining out of        the chamber back into the well bore.

Stage 2:

-   -   Via the internal control lines, a gas compressor (at the        surface) first applies gas at a pre-set pressure (170 psi) to        the odd numbered chambers and vents the pressure from the        even-numbered chambers. The gas flows through the gas line        within the line assembly and is released at the control panel        above ground level to be exhausted or re-circulated.    -   The pressurized gas in the odd chambers displaces the fluid,        causing it to flow to the even chambers directly above them,        with check valves preventing any downward flow. The control        panel directs pressurized gas/air to the top of even-numbered        chambers, and simultaneously vents the pressure on odd-numbered        chambers, causing fluid to rise from the even chambers to the        odd chambers above them.    -   The lowest fluid chamber empties and vents. The combination of        gravity and reservoir pressure from the well cause more fluid to        flow back into this chamber preparatory to repeat the process.        Fluid reaching the surface flows into the production facility.

FIGS. 15 A through 15 D show sketches of the installation process forthe Improved Fluid well pumping system 31. In the Installation ofSurface Equipment the final plumbing of the system uses a standardpumping tee to direct fluid flow and gas flow. The gas lines areattached to a connector at the pumping tee. The gas lines are connectedto the switching valves that are located on the control panel stand. Thefinal installation offers an aesthetically pleasing operationally safefootprint and a control panel that can be operated on electric or solarpower. The sketches are: Above ground pump system to control panel 81,Fluid and gas flow above ground manifolds 82, Gas lines, switch valvesand control panel 83, Solar power source 84, and an Aesthetic aboveground control system 85.

FIGS. 16 A through 16 C show additional sketches of the installationprocess for the Improved Fluid well pumping system 31. The installationof the NOJAK pumping system is a two pronged approach: the installationof the pumping chambers and surface equipment. The installation of theNOJAK pumping system is a simple operation that does not require theconnection of rods and tubing using a conventional pulling unit.

-   -   The installation of the NOJAK pumping system is a simple        operation that does not require the connection of rods and        tubing using a conventional pulling unit.    -   The NOJAK system is installed using a vehicle that has a powered        spool and a crane. The line assemblies are loaded onto the spool        and the crane is used to raise and lower the chambers.    -   The pumps are installed in the following steps:    -   1. The lowest chamber is lowered into the well and attached to        the line assembly. It is stabilized by an attached ballast        weight.    -   2. A cable grip is attached to connect the support cable to the        pump chamber and a chamber is attached at the end of a line        assembly.    -   3. The process is repeated until all of the chambers and line        assemblies have been placed in the well.    -   4. The system is then landed into the well head using standard        well head components using either a mandrel or slips type tubing        hanger.

Virtually all of these attachments are accomplished by means of fusionwelding. Normal mechanical fasteners and redundant sealing is avoided.The ends of the Pex and polyethylene are first heated by a hot plate(heated surface) to each of the ends of the components being fuse. Theplate(s) are removed and next these ends are brought together andpressure fitted. The seal is permitted to cool. The polyethylene is acrystalline material. As the junction of the two ends cool, the newjoint re-crystallizes to a state like the original base materials. Theprocess eliminates fasteners, uses a process familiar to target customerbase, is stronger than base material and improves the seal. Theinstallation sketches are: the Pump system being installed with servicetruck 86, connecting the chamber to line assembly 87, and top of groundtransition from pump system to well head 88.
